DESCRIPTION
The PGA202 is a monolithic instrumentation ampli-
fier with digitally controlled gains of 1, 10, 100, and
1000. The PGA203 provides gains of 1, 2, 4, and 8.
Both have TTL or CMOS-compatible inputs for easy
microprocessor interface. Both have FET inputs and a
new transconductance circuitry that keeps the band-
width nearly constant with gain. Gain and offsets are
laser trimmed to allow use without any external com-
ponents. Both amplifiers are available in ceramic or
plastic packages. The ceramic package is specified
over the full industrial temperature range while the
plastic package covers the commercial range.
